摘要：This paper examines renegotiation design in contracts for outsourced information technology (IT) services. Whereas prior literature in information systems has highlighted the likelihood of ex post rent seeking engendered by renegotiation, we build upon literature on incomplete contracts to posit that renegotiation can be Pareto improving by incorporating contingencies revealed ex post. Research on contract renegotiation has been hampered by two sets of challenges: the lack of appropriate data ...

摘要：Entrepreneurs that were employed by successful industry incumbents prior to founding tend to confer advantages on their new organizations. We propose and then demonstrate a similar network progeny effect rooted in the social relationships that form among entrepreneurs. Our analysis of new entrants into the Ontario wine industry shows that prefounding friendship ties of the founders of one especially prominent entrepreneurial firm led to significantly higher ice wine prices. This attests to the...

摘要：This paper examines whether and how differences in investors' information environments (measured by a country's information disclosure, accounting standards, and financial transparency) are related to cross-country differences in the market risk premium volatility. We use the vector-autoregressive and implied cost of capital methods to extract time variation in risk premiums for 41 developed and emerging markets worldwide. Consistent with theoretical predictions, countries with better informat...

摘要：Consumers become satiated with a product when purchasing too much too quickly. How much is too much and how quickly is too quickly depends on the characteristics of the product relative to the time interval between consumption periods. Knowing that, consumers allocate their budget to products that generate less satiation effects. Retailers should then choose to sell products that induce minimal satiation, but usually this is operationally more costly. To study this trade-off, we provide an ana...

摘要：The interface between an emergency department and internal wards is often a hospital's bottleneck. Motivated by this interaction in an anonymous hospital, we analyze queueing systems with heterogeneous server pools, where the pools represent the wards, and the servers are beds. Our queueing system, with a single centralized queue and several server pools, forms an inverted-V model. We introduce the randomized most-idle (RMI) routing policy and analyze it in the quality- and efficiency-driven r...

摘要：We consider a team of agents with limited problem-solving ability facing a disjunctive task over a large solution space. We provide sufficient conditions for the following four statements. First, two heads are better than one: a team of two agents will solve the problem even if neither agent alone would be able to. Second, teaming up does not guarantee success: if the agents are not sufficiently creative, even a team of arbitrary size may fail to solve the problem. Third, defendit numerus: whe...

摘要：In the pharmaceutical industry, measuring the importance of informative and persuasive roles of detailing is crucial for both drug manufacturers and policy makers. However, little progress has been made in disentangling these two roles of detailing in empirical research. In this paper, we provide a new identification strategy to address this problem. Our key identification assumptions are that the informative component of detailing is chemical specific and the persuasive component is brand spe...

摘要：We investigate whether public opinion influences the level and structure of executive compensation. During 1992-2008, the negativity of press coverage of chief executive officer (CEO) pay varied significantly, with stock options being the most criticized pay component. We find that after more negative press coverage of CEO pay, firms reduce option grants and increase less contentious types of pay such as salary, although overall compensation does not change. The reduction in option pay after i...
